Title: Improvements in or relating to apparatus for displaying advertisements and the like
IPC: G09F11/04
Filed: 1944-04-22
Abstract: 577,392. Moving advertisements. JOHNSON, J. April 22, 1944, No. 7510. [Class 3 (i)] Apparatus for displaying advertisements &c. to which various motions can be applied, comprises a cabinet 10 divided into upper and lower compartments 11, 12. Each compartment carries a shaft 28 rotated by a motor 42 of any form, or by manual power, through belt gearing 43, 44, 45, 47, 48, 48a and lay shafts 19. Each shaft 19 has splined on it two connected pinions 21, one of which is complete and the other gapped. Either pinion can be adjusted into engagement with a toothed wheel 27 on the shaft 28 by a thumb-screw 24, the complete pinion giving a continuous rotation to the shaft 28 and the gapped one an intermittent motion. A block 29 fitted with press balls 30 can be adjusted into the path of the teeth of the wheel 27 to hold the latter stationary during the drive intervals when the gapped pinion is functioning. The shaft 28 carries a crank 32 at its outer end, and is also recessed. The recess receives a display disc 52, which is viewed through a window 15 in the front of the compartment, and which has thus imparted to it a continuous or interrupted turning movement, as desired. Alternatively, the disc 52 can be removed, and replaced by a panel carrying guides on its back, whereby a display card can be reciprocated either vertically or horizontally. To impart this motion to the display card, it is connected to either a vertically sliding block 37 or to a horizontally sliding block 38. The block 37 moves on a fixed vertical guide rod 35, being reciprocated by a connecting rod 39 joining the block to the pin of the crank 32. Similarly, the block 38 moves on a horizontal rod 36 under the control of a connecting rod 40. Both blocks 37, 38 may be moved simultaneously by the crank 32, or either, or, as shown in compartment 11 in Fig. 2, both, may be disconnected from the crank 32 and held out of the way by a depending bracket 41. In a modification, the blocks 37, 38 are replaced by a single block slidable on a radius rod which can be adjusted around a circle to any desired angular position. The glass fronts 13 of the compartments 11, 12 are removable for changing the displays, and any number of such compartments may be provided.

Title: Combined safety valve and check valve for flowing steam or liquid
IPC: F16K15/18
Filed: 1935-03-11
Abstract: 450,336. Safety valves. CLORIUS, O. T., 6, Vesterfaelledvej, Copenhagen. March 11, 1935, No. 7576. Convention date, March 9, 1934. [Class 135] In a safety-valve construction in which the safety-valve member 5 is connected with or controls a valve 11 which closes to isolate the high-pressure side 2 and vent the low-pressure side 3 when the safety-valve 5 blows, a projection 16 on the valve casing encircles the valve 11 in its open position so as to prevent the flowing fluid from blowing or sucking it to its seat 10 before the pressure for which the which the valve 5 is set is attained. The valve 5 is loaded by a weighted lever 7 but may alternatively have a spring load. The projection 16 is formed on a closure cap 14. A piston 15 on the safety valve 5 prevents any appreciable escape of fluid before the valve 11 is clear of the projection 16. The fluid escaping past the valve 5 instead of passing directly to the atmosphere may be conducted by a pipe to a well. The Specification as open to inspection under Sect. 91 also describes a flange 17 on the member 5 against which the escaping fluid impinges to produce a high lift. This flange is shown but not described in the Specification as accepted.

Abstract: 972,849. Pneumatic tyre manufacture. GOODYEAR TIRE & RUBBER CO. March 1, 1962 [May 9, 1961], No. 7975/62. Heading B7C. [Also in Division B5] In the manufacture of penumatic tyres, the adhesive used for bonding the splice of the tread to the cushion rubber or tyre carcass contains a solvent dispersible rubber which is a diene polymer similar in nature to that present in the tyre tread or carcass and migratory acetoneextractable components present in an amount sufficient to maintain a balance between said components and a migratory acetone-extractable and normally liquid material present in one at least of the tyre tread or carcass, the acetoneextractable and normally liquid material being present in the tyre tread or carcass in an amount from 25 to 150 parts per 100 parts of rubber in the tyre tread or carcase. The tyre tread may be of diene rubber, e.g. a polymer of a conjugated diene such as isoprene, butadiene or di-methylbutadiene, or a copolymer of a conjugated diene and an arylolefinic monomer such as styrene, containing 25 to 150 parts by weight of a compatible softening oil per 100 parts of said diene rubber, and the adhesive layer may contain a diene rubber similar in nature to the rubber of the tread and 25 to 150 parts per 100 parts of diene rubber of the reaction product of a para hydrocarbon substituted phenol and an aldehyde present in an amount sufficient to maintain an equilibrium between said oil and said reaction product. In the tyre tread the compatible softening oil may be compounded with the diene rubber in such a way that it will develop an increase in modulus on ageing. Similarly the adhesive layer may be so compounded that it will develop an increase in modulus of the rubber on ageing of a value similar to that developed in the tread. The acetone-extractable component of the adhesive composition may be any resinous composition capable of producing tack and when not capable of producing tack it may be used in combination with a tack-producing component such as the ester of mono- or polycarboxylic acid esterified with a polyhydric alcohol. Lists of tackifiers are given.

Abstract: 645,442. Magnetic recording and reproducing apparatus. BARRETT, E. L. March 17, 1948, No. 7978. Convention date, March 22, 1947. [Class 40 (ii)] In a magnetic tape recording apparatus, the tape is made of paper coated with magnetic powder and is stored in an accordion-like arrangement in a casing or cartridge which has openings from which, and into which, the tape is passed. In one form, as illustrated in the exploded view in Fig. 4, the tape 49 is pulled from the opening 54, past the erazing and transducing heads 39, and pushed into the opening 53, by a rubber-tyred driving-wheel 58 on a motor 60, reduction in linear velocity of the tape 49 being accomplished by means of a friction-wheel 62 which is driven by the motor shaft 61 and is rigid with the driving-wheel 58. The tape 49 is guided around the casing in a groove 57, in which are provided gaps 67 into which, and from which, the heads 39 are inserted and withdrawn. The motion of the tape may be automatically arrested at a certain point in its length by means of spring-loaded pins 72 which may enter the holes 68 in the tape 49 and come into contact with a metal strip 71 and close the circuit of a relay which opens the circuit of the motor 60. Another driving wheel may be provided near the opening 54 for the purpose of driving in the reverse direction when required. Means are provided for indicating the extent of travel of the record, by marking a part 76 of the tape in a definite colour, such as red, and making the casing of a transparent material. An indicator scale 77 may be also provided for this purpose. The transducer heads 39 may have a gap G at an angle other than normal to the direction of travel of the tape, so that only a small portion of the creased part C, Fig. 9, of the tape 49 is over the gap G at any instant. Another construction is described with reference to Fig. 23 (not shown), in which an endless tape is not used, but in which the tape is pulled from one compartment and pushed into another compartment.

Abstract: 773,984. Transistor and discharge tube. amplifying circuits. METROPOLITANVICKERS ELECTRICAL CO., Ltd. April 15, 1955 [March 19, 1954], No. 8139/54. Class 40(6) In a circuit for amplifying small wanted signals #v, two similar amplifying channels are arranged to float, one in the sum of the unwanted and unwanted signals v + #v, and the other on the unwanted signal v so that only the wanted signal is amplified in each channel, the unwanted signal signal being eliminated in a differential device. The amplified wanted signal is derived by means of a differential device such as a differential circuit or an oscilloscope. The discharge tube V3 is energized from capacitor C1 de-coupled from tht supply by resistors R1, R3. The input at terminal 1P1, v + #v is applied over resistor R3 and appears at the output OP1. The input signal v applied at terminal 1P2 is fed over capacitor C3 to the grid of discharge tube V3, an amplified version m#v appearing at the anode, so that the total signal at OP1 is v + #v (m + 1). In a similar manner the tube V4 provides an amplified signal v-m8v. The signals at OP1, OP2, are subtracted to give an output (2m + 1) #v. In a modification, Fig. 2 (not shown), the input and output are applied over cathode followers. A number of similar stages may be cascaded. In a further modification Fig. 3 (not shown), the discharge tubes V3, V4 are replaced by transistors operating with common emitter connections. The resistors R1, R3 are so large that input cathode followers are not necessary. The circuit may be employed to obtain a push-pull output from a singleended source.
